Doctor discovers Master's hidden TARDIS

The Doctor and his companions examine anomalous energy readings at the Newton Institute and trace the signal to a massive mainframe computer. The Doctor identifies the unexpected source as the Master’s TARDIS, hidden within the institute’s technology. The revelation underscores the immediacy of Kronos’ impending arrival, as the temporal disruption from the stolen ship’s presence threatens to accelerate the entity’s destruction of time itself. The discovery forces the Doctor to confront the true scale of the Master’s scheme and the urgent need to dismantle the TARDIS before Kronos is fully unleashed. "key_dialogue": [ "DOCTOR: There are two things I don't quite understand, though. One is the massive power build up that you had, and the second is the strength of the signal that I received on the time sensor.

Doctor's Personal Time Sensor

The Doctor’s portable time sensor serves as the critical diagnostic tool for interpreting the chaotic temporal readings in the lab. Displaying erratic green numbers and emitting a pulsing low hum, it guides the Doctor’s analysis and ultimately points toward the mainframe’s hidden nature, turning suspicion into revelatory certainty.

Before: Fully assembled in the Doctor’s possession, powered and functional with loose wires connecting to his improvised belt power cell
After: Still active, readings now explained and contextualized, remaining a vital instrument in the unfolding crisis
Master's Chrono-Masking Mainframe

The massive mainframe computer unit, a behemoth of black metal and humming circuitry, dominates the lab visually and energetically. Initially appearing as institutional equipment, it becomes the revelation’s fulcrum when the Doctor exposes it as the Master’s TARDIS, its outer shell masking the stolen ship’s temporal core and controls.
